What happened to the dinosaurs? Conservative Bible interpreters generally believe they existed but became extinct before the Flood or after it. [source][source][source]
"Before the Flood, dinosaurs and man lived together on our planet. Extinction of the great marine reptiles, along with the majority of all other types of sea creature, would have been caused by the violent upheavals of the Flood, many being buried and preserved as fossils." [1][source]
